Limit plot to Max of One Candle

[Gupta]

Hi, I have the following code:

def yesterdaysClose = if close(period = "DAY")[1] < open(period = "DAY")[1] then close(period = "DAY")[1] else double.nan;

plot yc = yesterdaysClose;

That is running on a 1min 30 day chart. I want the plot to return one candle per trading day. And if possible though I don't think it is, return the time of the one candle that is plotted.

Here is a better example of what I mean. It is much more complicated but It is better to do it right I suppose.

def secondsTillClose = secondsTillTime(marketCloseTime);
def marketOpen = if secondsFromOpen >= 0 and secondsTillClose >= 0 then 1 else 0;

def newDay = if getDay() != getDay()[1] then 1 else 0;

def yesterdaysClose = close(period = "DAY")[1];

if low < regHoursLow[1] then low else regHoursLow[1] else low;

# First Market Open Candle
def yc = if marketOpen then yesterdaysClose else double.nan;
def o = if marketOpen then regularHoursOpen else double.nan;

# Gap up or down
def gapUp = if yc < o then 1 else 0;
def gapDown = if yc > o then 1 else 0;

# Half of gap
def hg = o + (yc - o) / 2;

def gapRemaining = if gapUp then
    Max(regHoursLow - yc, 0) else
    if gapDown then Max(yc - regHoursHigh, 0) else 0;

def percentRemaining = 100 * gapRemaining / AbsValue(yc - o);

def gapFilled = if percentRemaining == 0 then 1 else 0;

def halfGapFilled = if percentRemaining <= 50 then 1 else 0;
    plot gH = if (gapUp and !gapFilled and marketOpen and !newDay[-1])
    then regHoursLow else if (gapDown and !gapFilled and marketOpen and !newDay[-1])
    then yc else double.nan;

plot gL = if (gapUp and !gapFilled and marketOpen and !newDay[-1])
    then yc else if (gapDown and !gapFilled and marketOpen and !newDay[-1])
    then regHoursHigh else double.nan;

plot hGF = if !gapFilled and marketOpen and !newDay[-1]
    then hg else double.nan;

# Candles below half plot hGF are plotted, return 1 for gapup, return 2 for gapdown
def return1 = gL - (gL*0.001);
def return2 = gH + (gH*0.001);

# regHoursLow and regHoursHigh describes the lowest and highest candle after RTH open and before RTH close for equities
plot greaterlessGF = if regHoursLow <= hGF and GapUp then return1[1] else if regHoursHigh >= hGF and GapDown then return2[1] else double.nan;

# Coloring
gH.SetPaintingStrategy(paintingStrategy.DaSHES);

gH.AssignValueColor(if gapDown then color.darK_red else color.dark_green);

gL.SetPaintingStrategy(paintingStrategy.DASHES);

gL.AssignValueColor(if gapDown then color.darK_red else color.dark_green);

hGF.setStyle(curve.LONG_DASH);

hGF.SetDefaultColor(color.dark_gray);

AddCloud(gH, gL, color.gray, color.gray);

I feel like I am making this more complex than it should be. I am adding a plot that counts all RTH Barnumbers and trying to make it so if the barnumber of plot greaterlessGF is greater than first value of RTH Barnumbers + 1 to not plot it but I cannot get it working.

hello and welcome
yes, your questions are confusing. unfortunetely, that tends to happen, when someone doesn't know how to answer their own questions, they also have trouble describing the situation.

in the first part of post1 asks about a previous day price level.
the 2nd part has code for gaps.. i don't see how they are related ??

your variable name, greaterlessgf is confusing , and causes me to focus on it and try to make sense of it ,instead of the formula.

your post2 words are confusing. i don't know what you want to plot. what do you want to see on the chart?

try to list out what to want the code to find, without using specific code.

do you want,
.. every day,
.. find the first occurance of some condition,
.. then ? plot an arrow?

My post was edited by an admin to include my first question and my reply together because someone said the first question was not clear.

In the picture the gold line is the plot I want to edit known as greaterlessGF (Greater than less than gap filled),
I want the gold line to only plot the first time a candle is below the blue line which is plot hGF which stands for half gap filled.

What I was trying to achieve, is that for no matter how many times a plot may be true condition wise to only plot the first candle it is true during real time hours over many days. So for every trading day there should be a max of one candle plotted or one gold line.

Instead of looking like the first picture with the gold plot going all the way to the end of RTH hours I want it to look like this picture. This is important for code I want to make later on

i'll do some experimenting

you need a way to wait for a signal to go true and latch it. here are some examples.

in the meantime, does this help at all?
it shows when a gap is filled.

I think I did it. This is a not a perfect solution at all because it still plots two candles so if I wanted to make it into a chart bubble it would be difficult but you can't see a one candle plot anyways. Not sure if this is smart to do multiple times because I just created two plots to make the one I want.

I tried to use the examples but I could not figure out how to include the condition of it being RTH and the others seemed to require two conditions to be met not one. It lead me to this solution though

def return = if gH > gL then  gL - (gL*0.001) else gH + (gH*0.001);

def greaterlessGF = if regHoursLow <= hGF and GapUp and MarketOpen then return[1] else if regHoursHigh >= hGF and GapDown and MarketOpen then return[1] else double.nan;

def notglGF = if marketOpen and isnan(greaterlessGF) then return[1] else double.nan;

plot first_signal = if !isnan(notglGF[1]) and !isnan(greaterlessGF[-1]) then return else double.nan;

Edit:

Nvm this fixes the two candle problem. Still takes a lot of calculation though.

plot first_signal = if isnan(notglGF) and !isnan(notglGF[1]) then return else double.nan;
